WASHING 'MA 1 Application filed June 20, 1921. 3eria1 No. 478,994;

To all whom it may concern:

Be it known that I, SIDNEY R. BOARDMA'N, a citizen of the United States, residing at Los' Angeles, in the county of Los Angeles and'State of California, have invented new and useful Improvements in Washing Machines, of which the following is a specification. 7

My invention relates generally to laundry appliances, and more particularly to a washing machine that is adapted for household purposes, the principal objects of my invention being to generally improve upon and simplify the construction of the existing forms of similar types of washing machlnes, to provide a relatively simple, strong and durable structure that is capable of being easily and cheaply produced, to provide a washing machine wherein the operating parts are power driven, and further to provide a machine wherein the articles to be laundered are arranged within a rotatably mounted cylinder having a reticulated wall, in order that water maybe continuously forced throughv the container and thereby rapidly and' effectively performing the cleansing operations.

With the foregoing'and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in T the accompanying drawings, in which;

Figure 1 is a top plan view of a washin machine of my improved construction. IFig. 2 is a vertical section taken on the line 22 of Fig. 1;

Fig. 3 is an end view of the washing machine, said view being taken looking in the direction indicated by the arrow 3, Fig. 2. e,

Fig. 4 is a horizontal section taken on the line 4 1 of Fig. 2.

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10 designates the main body portion of the machine, the same being preferably constructed of sheet inetal, and in the form of a container or receptacle having a curved bottom 11 and a top 12, the latter being formed in two parts, and one part being hinged to the other in order to give ready access to the interior of the receptacle 10.

Arranged for rotation within the container 10 is a cylindrical cage that comrails or bars 14 serve as supports and points I of attachment for segmental sections 15 of reticulated material, such as wire netting, and which combine to form the horizontally disposed cylinder or cage that is adapted to.

contain the articles to be laundered. One of the reticulated sections 15 is suitably hinged to one of the cross bars 14, and its opposite edge carrying a suitable button or catch 16 is adapted to engage the corresponding cross bar, thereby providing a door for the reticulated cage to permit the insertion and removal of the articles to be laundered.

The discs 13 are provided with centrally arranged outwardly projecting trunnions 17 that are mounted for rotation in suitable bearings in the end walls of the receptacle 10, and one of these trunnions is extended through bearings formed in a bracket 18, and mounted on said extended trunnion between said bearings is a bevel pinion 19.

The receptacle or container 10 is supported in one end of a suitable framework 20, and arranged in the lower portion thereof is a horizontally disposed plate or table 21 in the center of which is formed an openin 22. Mounted for rotary movement in suitable bearings 23 on this table is a transversely disposed shaft 24 that carries a beveled gear wheel 25, and meshing therewith is a pinion 26 that is carried by the shaft of an electric motor 27 and which lat- -ter is mounted on table 21. The outer end of shaft 24 carries a beveled pinion 28 that meshes with a corresponding pinion 29, and the latter beingfixed on the lower end of a vertically disposed shaft 30. This shaft is journaled in a suitable sleeve 31 that depends from the bearings 18, and the upper .end of said shaft carries a bevel pinion 32 tubular member 35, and a short tubular member 36 connects the upper portion of the chamber within cylinder 33 with the upper portion of the chamber within receptacle 10.

Arranged for reciprocatory movement within cylinder 33 is a piston 37 that is carried by the lower end of a piston rod 38, the latter passing through a bearing 1n the center of cover plate 34, and being connected to the central portion of a cross bar 39. Pivotally connectedto the end portions of this cross bar are the upper ends of vertically disposed connecting rods 40, the lower ends thereof being journaled on cranks 41 that are formed on the ends of a shaft 42. This shaft is 'transversely arranged upon table 21 and is mounted for rotation in suitably located bearings 43. Fixed on said shaft is a relatively small sprocket wheel 44 that is engaged by a sprocket chain 45, the latter passing around a relatively large sprocket wheel 46 that is fixed on shaft 24.

In the use of my improved Washing machine, the articles to be laundered are placed in the reticulated cylinder 15, and the receptacle or container 10 and cylinder 33 are partially filled with'heated water to which soap or like detergent has been added. As motor 27 is operated, the rotary motion of its shaft is transmitted through pinion 26 and gear wheel 25 to shaft 24, and the rotary motion of said shaft is transmitted through pinions 28 and29 to vertical shaft 30, and through pinions 32 and 19 this rotary motion is transmitted to the reticulated cylinder 15 so that the latter is rotated within the container 10, and during such rotation the articles within said cylinder will be continuously agitated and turned over and over within the body of water contained in the receptacle 1() Simultaneously with the operations just i described, the rotary motion of shaft 24 will be transmitted to shaft 42 through sprocket chain 45 that connects sprocket wheels 44 and 46, and as shaft 42 is thus rotated, the cranks 41 on the ends thereof through connecting rods 40 transmit vertical reciprocatory movement to piston rod 38 and piston 37. Obviously as the latter moves vertically within cylinder 33 the body of water therein will,. as said piston moves down- Wardly, be forced through passageway 34 into the lower portion of the chamber with: in receptacle 10, and on the upward move.- ment of said piston any water that may have accumulated on the top of the piston will discharge through tubular member 36 into the chamber in'the upper portion of receptacle 10. Thus water from the lower portion of the chamber within cylinder 33 will be forced into and upwardly through the chamber occupied by the reticulated cylinder, and this surging movement of the water together with the constant agitation and turning over of the articles within the reticulated cylinder will very rapidly perform the cleansing operations.

The driving connections 44, 45 and 46 are arranged so that shaft 42 is rotated at twice the speed of the rotation of shaft 24, and thus with each complete rotation of the reticulated cylinder, piston 37 will make two complete strokes, so that the Water is forced four times through the chamber within receptacle 10 while said cylinder 15 is making one complete revolution.

A washing machine of my improved construction is comparatively simple, and by providing for the constant agitation of the articles to be laundered and the forcing of water in opposite directions through the rotary container, the cleansing operations may be very rapidly and effectively accom- I plished.

It will be readily understood that minor changes in size, form and construction of the various parts of my improved washing machine may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

1. A washing machine havin a pair of chambers, the lower portions 0 which are communicatingly connected, a reticulated cylinder arranged for rotation in one of said chambers, a piston arranged for reciprocatory movement in the other chamber and adapted to effect a flow of water first in one direction and then in the other through the connection between the lower portions of said chambers, and means for rotating said reticulated cylinder and reciprocating said piston;v

2. In a washing machine a pair of chambers, the lower portions of which are communicatingly connected,a reticulated clothes container arranged for rotation in the lower portion of one of said chambers, and a piston arranged for reciprocatory movement in the other chamber and adapted when operated to effect a flow of water first in one direction and then in the other through the connection between the lower portions of said chambers.

3. In a washing machine, a pair-of chambers, the lower portions of which are communicatingly connected, a reticulated substantially cylindrical clothes container arranged for rotation in the lower portion of one of said chambers, a piston arranged for reciprocatory movement in the other chamber and adapted when operated to effect a flow of water first in one direction and then in the other through the connection between the lower portions of said chambers, and there being anopening between the upper portions of said chambers to permit water'that may accumulate in the upper portion of the piston chamber to return to the clothes receptacle chamber. 7

4. In a washing machine, two cylinders, one of said cylinders being provided with means for the agitating of articles to be washed and the other of said cylinders being provided with a piston, operating means for said agitating means and for said piston, 10 and additional members for the confining of SIDNEY R. BOARDMAN.
